Solid waste services

Residential garbage collection costs are recovered through a flat-fee set annually based on a full cost recovery model. Residents will continue to see an increase to solid waste collection fees. The fee increases in 2020 and 2021 will mirror the new solid waste collection contracts that were competitively tendered and recently awarded. The previous contract was awarded in 2012 and expires mid 2020. The costs for the new contracts reflect changes in market conditions since 2012, such as increased labour costs and higher equipment, maintenance and fuel costs. Furthermore, Multi-Residential services will see an enhancement in services, including the collection of bulky (large) items, green bins, and the introduction of garbage carts.

In 2020, Curbside services will be charged at a rate of $96.00 per unit per year while Multi-Residential service will be charged at a rate of $56.50 per unit per year.

In 2021, based on current projections, Curbside services will be charged at an estimated rate of $102.00 per unit per year while Multi-Residential service will be charged at an estimated rate of $68.00 per unit per year, based on collection contract increases only.

For the remainder of the term of the contract, solid waste collection rates are projected to increase annually at the average rate of inflation.

For more information on solid waste, refer to Solid Waste Management Services.

Where can I find the 23-digit account number for my financial institution's online banking?

The roll number shown on your tax bill is the account number that you will need to use. For our purposes, the only account reference needed can be found in the first 15 digits (starting with 0614). Different banks require different numbers of digits (ranging from 18 to 23). Generally, to match the number of digits required by your bank, you should enter extra zeroes at the end of your roll number until you meet the bank's requirements. If this does not work, contact your bank's helpdesk. If you have any questions or concerns, please contact us at

Does the City of Ottawa have a list of properties being sold because of unpaid taxes?

The City does sell properties from time to time because of unpaid taxes. If there is a sale taking place, the list of properties will be advertised in the Ottawa Citizen and Le Droit. You can also check the Property Tax Sale Process section of this site.

Will my payment on the interim tax bill be credited towards my final taxes?

Yes. The interim billing is to be treated as a “payment on account” and will be deducted from the final billing.

What does the number to the right of my name on the tax bill mean?

It is a sequence number used for the printing and mailing function. It has no relevance to the taxpayer or the tax office.

Why hasn’t my favourable Assessment Review Board decision been reflected on my final tax bill?

The tax bill must be paid as issued. The Education Act allows the municipality 120 days from the date in which the Assessment Review Board decision is released to process an adjustment on an account before interest is paid. If an adjustment is not reflected on your final tax bill but is within the 120 days no interest will be paid. Once the adjustment has been calculated the amount will be applied to your tax account and a letter will be sent identifying the amount. The person entitled to receive the refund will have the option of leaving a credit on their account or having a refund issued.

Why are tax payments due mid-month, and what if I make a late payment?

Property tax due dates are approved every year by City Council. Since more than 240,000 tax accounts must be billed and their corresponding payments recorded in a short time period, the third Thursdays of March and June were chosen to ensure payments could be properly recorded and in the bank by month’s end. Payments after the due date are subject to a penalty of 1.25 per cent.

My mortgage company pays my taxes. Why did I receive a bill?

We have no record of your mortgage company on your account. Contact your bank for instructions. You should request that your bank contact us to ensure we record their interest on your account. This will ensure all future bills will be sent to them. To avoid a penalty on your account you should contact your bank immediately.

Why am I still getting a bill if I’m on a pre-authorized tax payment plan?

It depends on the type of pre-authorized payment plan you belong to. For example:

  • If your pre-authorized payment plan calls for two payments per year on the instalment due dates, the bill is sent to inform you how much will be deducted from your account on the due date. The stub portion of your bill should indicate that you are on pre-authorized payment plan. If it does not, please contact Revenue Services at 613-580-2444 (Calls may be recorded) (TTY 613-580-2401) to ensure we have your proper information on your account.
  • if your pre-authorized payments are withdrawn monthly and you received a bill, please call Revenue Services at 613-580-2444 (Calls may be recorded) (TTY 613-580-2401) to ensure we have the proper information on your account.

How much of the year does the interim tax cover?

The interim tax bill is a payment on account towards your annual taxes. It does not cover a specific period of time. This interim payment will be deducted from your final bill, which covers the calendar year when it is issued later.


How your property taxes are calculated

Property taxes are calculated using the assessed value of the property determined by Municipal Property Assessment Corporation, (MPAC) multiplied by the municipal tax rates determined by City Council and the education rate determined by the Province.

Descriptive video: How your Property Tax is Calculated

Okay, I want to explain to you how your property taxes are calculated based on how much your home is worth. Imagine there is a town that only has three homes. And they're each worth a different amount. The total cost to provide all of their town's services is $1000. This is collected through property taxes. Each home owner pays property taxes based on how much their home is worth. So, the value of all the homes are added up and divided by the town's cost. Which gives us the tax rate. This tax rate is applied to all the houses to get enough money to pay for all of the services. So, each home owner pays according to how much their house is worth. Every four years, the houses are reassessed. Let's say all three properties have gone up equally, in value. If we go back to our calculation, the total cost of services hasn't changed, but the total property value has increased. When this happens there will be a decrease in the tax rate. Now, when we apply that new rate on all the homes, everyone still pays the same. Let's recap. One. Property taxes are based on what a home is worth. If reassessments all increase equally, then everyone pays the same taxes as before. Now, let's say another four years has gone by and these homes are reassessed. During this time, the house on the right became more valuable in the market than the other two. Okay, so, time for a little more math. The total value of all the homes have increased, which means the town has to calculate a new tax rate. With this new tax rate, the first two homes will actually pay less than the home on the right that was reassessed at a higher value. Since the cost of services hasn't changed, the town doesn't need to collect more property taxes. However, since property taxes are based on a home's value, those taxes could potentially go up or down, based on the rest of the homes. So, what happens when the cost to provide services goes up? Well, it means more property taxes need to be collected from every home and a new tax rate is calculated. To get the new rate, we take that amount that the town now needs and divide it by all of the property values. The new rate is applied to all the homes and now everyone has to pay the new tax amount to continue to fund all of the services. So, let's review. One. Property taxes are based on the value of a home. When homes are reassessed equally, each home owner will pay the same amount, proportionately, as before. Two. When homes are reassessed at different values, each homeowner will pay a different amount proportionately, based on how much their home increased in value. Three. When the town's cost to provide services increases – a property tax increase – then, everyone pays their share, proportionately, across the board. And that explains the relationship between property value and property taxes.
